Specification of Letters Patent.

Patented May 29, 1917.

Application filed October 6, 1916. Seria1No.12' ,171.

To all whom it may concern:

Be it known that I, FERNAND CAILLETEAU, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented new and useful Improvements in Attachments for Electric- Light Snap-Switches, of which the following is a specification.

This invention relates to improvements in attachments for electric light snap switches, and has particular application to a pull attachment for turn button switches. In carrying out the present invention, it my purpose to provide an attachment for turn button snap switches which may be quickly applied to the button of the snap switch, and whereby the snap switch may be turned 011 and off after the fashion of the chain snap switch, thereby eliminating the necessity of reaching for the button of the switch.

It is also my purpose to provide an attachment of the class described, which will embrace the desired features of simplicity, efhciency and durability, which may be manufactured and marketed at small cost, and which may be quickly and conveniently attached to any type of turn button switch, so as to convert such switch into a pull switch. With the above and other objects in view, the invention consists in the construction, combination, and arrangement of parts hereinafter set forth and falling within the scope of the claims.

In the accompanying drawings V Figure 1 is a perspective view of an attachment constructed in accordance with the present invention.

Fig. 2 is a view in elevation, showing the attachment applied to a turn button snap switch.

Referring now to the drawing in detail, 1 designates a turn button snap switch socket of any suitable or preferred construction, while 2 indicates my improved attachment as an entirety.

The attachment 2 embodies a block 3 formed with a transverse slot 4.- designed to receive the button or key of the snap switch.

'and having the opposite walls thereof formed with depressions 5 to accommodate the usual projections on the sides of the key. The outer edge of the block 3 is circular, and formed on such edge between the ends thereof is an annular row of teeth 6, surrounding the periphery of the block and disposed upon opposite sides of the row of teeth 6 are collars 7 formed with depending lugs 8 between which is mounted a weight 9 suitably fastened to the lugs 8. The upper portion of the collars 7 are formed with cars 10 and arranged across the space hetweenthe ears 10 is a pivot pin 11 having the end secured to the ears. Pivoted upon the pin 11 is a lever 12 formed, at one side of the pivot pin, with a depending dog 13 designed to engage the teeth 6, and having the end adjacent to the dog connected to one extremity of the depending pull cord or chain 1%. l5-15 designate securing elements formed of a single length of wire having one end bent at right angles to itself and journaled in a bore formed in the block 3 upon one side of the slot 4 in such block. These securing elements are disposed upon opposite sides of the slot 4 adjacent to the relatively opposite ends of the slot, and the outer end of the wires are curved in opposite directions as at 16, so that when the block has been placed upon the key or button, the securing elements may be swung inwardly toward each other to encircle the shank of the key or button, thereby holding the attachment against accidental disconnection from the button.

In practice, the weight 9 holds the collars 7 in normal position upon the block, and the dog 13 engages the adjacent tooth 6 on the upper side of the block. lVhen a pull is exerted upon the cord or chain 14, the attachment revolves as a unit, thereby rotating the button to close the switch, and after the switch has been closed and the cord. released, the weight restores the collars and the dog to normal position so that the dog may obtain a fresh grip upon the teeth of the block. When it is desired to open the switch, the cord may be again pulled so as to rotate the button to break the circuit.

While I have herein shown and described the preferred form of my invention by way of illustration, I wish it to be understood that I do not limit or confine myself to the precise details of construction herein described and delineated, as modification and variation may be made within the scope of the claims and without departing from the spirit of the invention.

I claim 1. An attachment for key snap switches comprising a block formed with a transverse slot to receive the key of the switch and having an outer circular edge, an annular row of teeth formed on said edge, collars surrounding the circular edge of said block at the opposite sides of the row of teeth thereon, and capable of movement relatively to the block, a weight depending from said collars to hold the same in normal position on the block and restore the collars to normal position, a lever pivoted between said collars above said block, a dog on said lever engaging said teeth, and a pull cord connected to said lever whereby the latter may be pulled to engage the dog with the teeth and rotate said block and key.

2. An attachment for key snap switches comprising a block formed with a transverse slot to receive the key of the switch and having an outer circular edge, an an- Copies of this patent may be obtained for five cents each, by addressing the nular row of teeth formed on said edge collars surrounding the circular edge of said block at opposite sides of the' row of teeth thereon, and capable of movement relatively to the block, a weight depending from said collars to hold the same in normal position on to normal position, a lever pivoted between said collars above said block, a dog on said lever engaging said teeth, a pull cord connected to said lever whereby the latter may be pulled to engage the dog with the teeth and rotate said block and key, and means carried by said block and encircling the shank of the key to prevent accidental disconnection of the block from the key.

In testimony whereof I aflix my signature.
